a new RG1527 is great so is a used RG7620 can be had for pretty cheap on the bay (i have this one, and most people will agree that they're a screaming deal.) korn actually used these models from time to time.
those models have the tremolo bridges as well as the RG7420 (lesser quality pickups, and the trem is very inferior to the one on the 7620)
the new schecters are turning out to be great products from what i hear lots of people saying.
the cheaper "damien" models are really quite good for lower-mid end guitar
then there are the "hellraiser" series which are a little more upscale... these have EMGs in them
and last but deffinetly not least are the "blackjacks" which are similar to the hellraisers but have
seymour duncan pickups... real ones, not "
duncan designed" which are the cheaper kind.
i highly reccomend going with a scale length of over 25 as it will give you alot more clarity that really shows up on the low B string... most if not all of these new schecter 7 strings have an extended scale length.
