Yes, of course, however judging by the fact the end of auction is only 3 days away, and the fact that it is only at 45$ right now...
here is a look at some other auctions going on right now...just to give a comparison.

This is a good point however. Just wanted to put this out there.

Dude, early-day auction prices mean absolutely nothing. Most people will use a sniping program to automatically bid their highest at the last minute.
Chances of scoring a bargain like that are minimal.
Also, getting it out into the community would be the *last* thing to do if you wanted to score a bargain. You know, given that they're auctions and
all.

I think 14/20 gear is heaps better than 24/40
a basic 24/40 for making up reagents and then the real funky stuff in 14/20 makes for
a safer lab I think.
keeps reaction sizes down and gives you the balls to try shit you would not in larger glass.
oh and ive had some of the kimble shit and shit is exactly what it
is.
second only to sam duck  as far as shit goes.

You don't recall certain... issues, with 14/20?
Methinks one of these is essential. Makes life a lot easier if you're not dealing with something particularly temperature-sensitive, at any rate.

Personally, I have never had issues with 14/20 glassware.
What issues would they be?

The relative ease with which a distillation can run away on you and start pumping liquid up your condensor and into your distillate.
Nothing that can't be avoided with patience and attentiveness.

That set (though with a one-necked RBF instead of three-necked) was my first set of ground glass. I remember buying it on eBay for about 150 USD like
three years ago. Boy, I was happy

Then you're obviously doing something wrong - what size of flask did you use? How much did you fill it?

I don't know what you actually bought, but i have a Kimble 24/40 set that I bought from Fisher in 1985.
I have bounced the RBF's off the tile floor in the basement, heated them under high vacuum, soaked them in KOH-ethanol and dichromate cleaning
solution, you name it.
I still have every piece of glassware that came in that set. No scratches, cracks or other problems.
Maybe what they sell nowadays is not as good as in 1985, but back then it was quality glass.

Yes, I've got one of them. It's great! I use it all the time.
From what I've heard as well, Kimble glass is in the higher range group.

Thought I replied to this... weird.
500ml round flask, filled ~350ml, so yes, that's a lot of it. Actually, what *is* the recommended max level in a flask for distillation?

Half full is what most people say. For some distillations (where bumping/foaming/flooding won't be a problem), like when distilling dilute ethanol, I
fill it maximum 2/3 up and take it slowly from there. A 500 mL flask with 14/20 fittings and condenser isn't good... There's a reason it's hard to
find flasks over 250 mL with 14/20 joints, you know!

No, Pyrex was the best. But Fisher only
sold Kimax kits at the time.
Actually I have a couple of Bomex beakers and condensers that so far have been OK.

Pyrex, Ace, Atmar, Kontes, and LabGlass are all good. Now I have been very impressed with ChemGlass, they have very good quality round bottom
flasks, as well as many other items. They are the heaviest wall flask around, good for vacuum work. You do need to heat them carefully, they are
best for mantles due to their thickness. But they resist getting star cracks better than any other brand in my hands (and floors).
I've only worked with a few cheaper glassware items, and would not worry about using them for beakers and erlenmeyers, but I would avoid them for
glass joint flasks. I have some economy beakers in my collection, and they look just fine for most work. My biggest problem with glassware has
been addition funnels, them seem to break easily, have poor stopcocks, and be poorly designed. The seem to break easier than anything else.
