i say if it's sitting at a good price, grab it! unless your handy with fittings and what nots. you got a link to the one your thinking about?

Here's the 50L w/ withdrawal: http://cgi.ebay.com/TAYLOR-WARTHON-LIQUID-NITROGEN-TANK-CONTAINER-/160565598486?pt=LH_DefaultDomain_0&hash=item2562749916#shId. Shipping to me would be around $100.
 
Otherwise there are some 30L like: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190512938906 that i am making/going to make offers on.

hummm, that's about 400 bucks out the door right now (2 days left)....you one of the bidders?

Nope not yet, but it's really temping if i could get it around that price. 
 
P.S. Don't go stealing it now that i posted the link.

oh no! never that rabid...that's not how friends get down.
 
i think you would be happier with that one though. that would keep you going for a bit.

Haha good to know.
 
Though it would be a fair bit more than a 30L if i can get a decent offer accepted on those, i feel like the 50L would be like "future proofing". Also if i had multiple people over for benching, we wouldn't run out as fast.
 
I do have one concern though. 50L would be hard for me to burn through quickly. When i benched with Deux and Chance, it took me and Chance 4-5 hours to go through 30L (q6600 for me, phenom ii 555 for him). So is it possible to have a dewar partially filled?

yes. it will keep longer if the dewar is kept in a cool place.ou can bench a few hours one day then bench some the next. you dont have to fill the whole 50L if you dont want too, but you have that option too.

Sweet, good to know. Now i just gotta make sure i can fit it in my car (measured, and should fit, though tight), and that i can lift it (128lbs full)...might need some help for that lol.

yeah, mine is pretty damn heavy when fully full. if it doesn't fit in your car..just take out the back seat if you have that option. it's what i do, but since i ran video and audio cables all through my car, the back seat just comes right out when i need to check for problems.

How many L is yours? Also, what brand/model?
