Welcome to the site, Southern California representing!
Good luck in your search, I have been considering trying to buy one too. Sometimes I want to obey but don't want to leave the room/not hang out with the family - practice a shooter or grind a RPG while the lady watches her shows, before I crash out, etc.
My PSP has served its purpose well with the types of games I've traditionally attempted - RPGS and such. The PSP is the only way I've played through Neutopia and it was great.
However I've recently been trying to up my shooter abilities, and have practicing Blazing Lazers so I can finally clear it (STFU I suck and know it). Playing it on the PSP sucks because of the ghosting and fps inconsistencies, and generally emulation feels off to me.
I've been wondering if the quality of the screen on the TE would be better (LCD Modded, or original, or both) than the PSP. The PSP has so much blurring and ghosting it makes playing shooters kinda hard, and I was hoping the TE/GT might be the best option, but after talking with blueraven and tucci I wonder if it is?
Regardless, good luck with your search and enjoy it once you get it - maybe you can post some insight after!
