I've had my Artcore AG75TBS for 4 years, and I've never regretted buying it. On occasion, I'll think about swapping out the humbuckers for single coils, such as Seymour Duncan Phat Cat or Gibson P94, but then I'll start jamming on it, and decide "nah." For me, the AG75TBS was an affordable alternative to lusting for a Gibson ES or L series.
I've also tried several of the Artcore AFS75T models, and although I don't completely dislike them, they weren't really suitable for what I was looking for, being a rockabilly box. I'd considered the possibility of modifying an AFS75T with single coils, but the tone from the ones I'd tried just didn't reach out and grab me...the "sparkle" wasn't there. Had I not already owned the AG75TBS, I could have seen me buying an AFS75T, but I wasn't really looking to duplicate something I already have, except with a vibrato tail piece, such as the AFS75T has. I eventually ended up with a Peavey JF2 EX, after having tried an entry level Gretsch Electromatic G5120 (when I had the money) that lost "the fight" for my bucks to a used Fender Bass VI.
If you have the chance, try as many Artcore models as you can, within your price range, rather than possibly limiting yourself to one or two model choices and ending up disappointed, when you don't find one of those you like.
