well for tourney, a A5 wouldnt really get you anywhere.
but yeh, dm4's are nice, you could be lucky and get a dm5 for about 310 maybe 300.
There are so many markers out there, and with it being a buyers market, there are some serious bargains to be had.
i know mike brumie (may be spelt different) has a really nice dm4 for sale, and there are plenty of ion banging about which you cant go wrong with.
