hey bro, i'm from san antone and i found this store here that did an awesome work on my ver4 ps2. the manager (Larry) and the tech (Chris) are very nice and professional. they did an wonderful job for me. i'm glad i found them 'cause i was kind of reluctant on sending it out via mail. but check 'em out and speak w/ them. i hope they can help you out.
btw, i think there was a place in your are that does mod installation. i'll look around and see if i can find them and i'll write back. but you might want to do a "google" search for this service in your area, that's how i found out about this store in my neck of the woods. let me know what you think about this company, okay.
