You can get an etek off here around the 220 mark for one in mint condish, and maybe an 06 for about 250-270. They're both great markers, so just see which one you like the feel of more.
i've used all of em mate, as i'm sure many of you guys have but if i was you i'd go for the new pm7 @250, i found that they are more accurate that the others and just an all round good gun. but i was in the same position as yourself not long ago and went for a used ego but had nothing but problems and had to send off the thing twice before it was fixed. then decided to splash out and get the dye dm8.
if i were you i'd spend a bit extra though and maybe look at a new etek2
