what kind of music do you like? that will help with the decision.
if you want something that you can play unplugged, and plugged in, the epiphone dot and ibanez artcore series are nice, they are semi-acoustic and are both a great start point.
for $800 you can get a really nice guitar buy if you might want to consider spending less on the guitar and more on a decent amp.
a crappy guitar into a good amp can sound decent, anything into a crappy amp will sound like crap.
also check out ebay for...
squier '51
squier deluxe series
epiphone les paul
edwards les paul (niiiice guitars)
fender telecasters/stratocasters
agile/sx also make pretty nice guitars for the price as well.
hope that helps
