Digitech RP series, Boss ME series, Zoom G series, Line6 pods, Behringer Vamps, Roland virtual guitar expensive stuff, some 'modelling' amps with dedicated recording out jacks (Peavey Vyper is the one I used)... look at any online music catalog like musiciansfriend, zzounds, sweetwater, AMS, samash etc etc and you will see loads of them - pretty much the same manufacturers and products and prices over and over again it gives a pretty good idea of what's out there.
Common things to most new guitar multieffects pedals are amp simulation/cab emulation for direct recording and USB out are the norm nowadays. Only the absolute bottom end of multieffects don't have USB out - and I don't know of any made anymore except the Boss ones that don't use amp sims instead of just basic effect settings for dirty sounds (think "distortion"+ "4x12" versus "Peavey 5150" or "Dual Rectifier" as examples - kind of annoying actually).
If you don't care and just go with an audio line, good for you, you might save 50 bucks but you have to deal with line levels and soundcard 1/8" 'mic' jack inputs, stuff that makes for poopy quality if you aren't careful.
A multieffect pedal that works live but can also be plugged in direct for recording sounds like what you are after and there are loads and loads of options for them these days - season to taste I guess, but I can't stand the digitech RP distortion sounds but like the rest of the effects, don't like the Line6 gimmickyness of too many amp sims (about a handful of which are actually useful), don't trust Behringer endurance for a live pedal, find zoom to sound good, but pretty non-intuitive interface for programming, and Boss, while sounding top notch, is pretty bare bones no-frills - they all have their ups and downs but all of them have more ups than downs IMO and I have never met a multieffect pedal that I didn't like at least something about.
As a personal miff with Guitar Center I want to point out that their role in things is to get rid of what they have in that store at that time, like a car dealer. You won't always be shown all the options, some brands they do not carry at all and act as if they don't exist, while others they push and push like they get some kind of incentive program from the company. Going to a guitar center to shop around is like going to a car dealership - you either know what you want or be prepared to get a sales pitch and a line of BS just to sell you something. My advice is to check out online gear catalogs to see all the options, then hit the music stores to try out what you are curious about - not the other way around.
