I have a First Strike FS1, think I paid a little over two hundred for it about three years ago.
I like it, it works good. No lock on dvb-S2, but it does show S and Q for S2. Rugged too, which is important for me, I've dropped mine a few times when my legs have given out, when it's take a dive off of the ladder or drop the meter, meters going!
I have had to resolder the plug in it for the power pack, but I think that's from me dropping it with the power pack hooked up. The battery doesn't last long anymore either, I can get 25 minutes or so out of it now, when it was new, probably an hour, hour and a half.
Really like it though and like Pacificrim said, it's easy to setup. You can program in a bunch of custom sats, too. I've read that there is knock offs made of the FS1, so that's something to keep in mind if you see a screaming good deal on one somewhere.
