Personally I find the LA to be quite welcome on my game shelf. Being a 100% front loading system that is built like a tank, I can stack things on it and it's still fully playable. I RGB modded mine, so all my PCE and Sega games look purdy (LD games are composite only of course). I even ended up with a USA Genny Pac to get around the SegaCD region lock for playing my Working Designs originals here on my Japanese LA unit.
And finally, while the actual LD game library is small it has some really good titles. Sure price is insane for a lot of them, but I've gotten my money's worth. Hell playing the absolute cheese fest Dr. Paolo in 3D is almost silly enough to justify the entire system imo.
