Just a link, I like it: http://www.mcarterbrown.com/forums/paintball-news/215877-new-pump-spyder.html
I've been selling them, they are super-hot over here. Most put a 13/3000 tank-stock on the back for 500 shots. You get about 2000 shots from a 20oz tank. It feels a little more plasticy than it looks, but for the money it's unbeatable. I actually really like the MR5 too. Spyder are on the up. They'll have a good 2013.
If these were £80 ($129) I could see people that don't normally go for a pump get one, cheeper than a pistol for scenario guys, for supair cheep enough for a team to get, to improve their playing on ltd paint, would be a great training tool. But you cross over the £100 mark, you are going to have to want one to buy it.
I wish pump would stop being considered as a method for sup'air teams to 'work on their technique'. It's a load of bollocks.
Pump is a great format in it's own right... it's all about quality not quantity If you are crap at Supair you will probably be crap at pump as well
