if u want a reasonably affordable linear tattoo machine , go for the Neo-Tat. It dont need to use rubberband on the needles. its runs real smooth and almost maintenance free, and there are 3 different stroke length to choose from. and lastly Ray is a awesome guy to deal with!

if u have more budget to play around with, also look into the Bishop by franco , or the Rapier, by tattooedpirate. these are sweet machines too!!
