hi and welcome to namepros! Take your time and do plenty of research before venturing out into 2 word dot coms. Your safest avenue is to invest in some 4L.coms (L = Letters). Definitely read up on all you can. LiveCrisp.com isnt a bad domain, i would value this one at reg fee plus $75 - $300 reseller
enduser: $500 - $1250
you might want to pick up the .net and .org of this one just to make it more appealing.
I like it because crisp and chips (uk vs us) could be a casino blog site with a play on words or something. good luck.
