Yamaha DTXpress/DTXplorer/DTXtreme

Wow thanks guys, great help. Well i went round i negotiated £550 for 
it, it's in really good condition with only a little wear on the 
bass pad (light discolouration), everything triggers well and the hi-
hat and snare work simultaneously. I played most of the preset kits 
and they seem fine, i played along to the preset songs with the 
click and they seemed ok. I used the guy's headphones (full volume) 
and noticed the sound was particularly quiet, but louder than the 
actual sound of me playing, I asked him about this and he said they 
were special recording headphones and that normal headphones would 
be a lot louder. Other than that i was most impressed by the upkeep 
and condition of the kit, he had all the boxes and instructions. As 
for MIDI he said he did connect it externally and used it for 
recording, I don't think he ever tried plugging a CD player in the 
aux jack. As for the guy himself he was really cool and helpful and 
explained he was moving to the states (LA) as he had just got a 
record deal with Interscope records. He is in a band called the 
Davey Brothers and he gave me some free CD's and a DVD which i 
checked out and was most impressed by. The guy himself plays bass 
and sings, and they distributed, produced and recorded there first 
album by themselves, in the UK it sold around 3,000 copies. So look 
out for them, i think they'll be big.
