I recently got a Dye DAM off of the forum and I love it. I was looking at various markers and whenever I thought I had found one there was always someone able to offer a good and bad point for it. Tommikka was very helpful and I appreciated his help (and patience!) throughout!
I was considering a DAM, BT Delta Elite, G36 Elite, Etha with EMC kit, Tippmann X7 Phenom to name a few!
It does come down to why you want one, I was a bit vain and wanted one that was good but also looks good. I tend to go to walk ons where there is space because it's only half booked by stag parties/etc. So I am not a hard-core paintballer by any means. One of the guys I go with has a BT Delta and it's very good. He said it's simple to maintain from using you-tube videos etc. After talking with him I went for the Dye Dam. I haven't used it much, but I stripped it down and cleaned and lubed it all before my first shot of if. I found a good film on youtube as well for this and found it very easy to strip and clean.
I haven't had any problems with the DAM (yet...), but two of the guys I know from the local site seem to have had 'issues' with theirs.
One of the main benefits of the DAM is the ability to have a magazine and a hopper - so you can have First Strike rounds in the Magazines for when you want that bit more distance and accuracy for the smug person who is teasing you by being just out of range, then switch quickly back on to hopper for some close quarter action!
