I have the A5 Golden Oster clippers, and they aren't wonderful (A little loud, and the hot air gets blown onto your hand sometimes (at least it's not the horse!) ) but they aren't horrible, either. The blades stay cool for a long time, I've done some heavy duty clipping and they're fine, and I have all kinds of blade for them, hehe. I do enjoy them a lot, actually.
I also have a small wahl cordless pair that I don't fancy too much. You can't change the blades (they're #30), it broke in about a year with VERY little use, they don't hold a charge... If you could change the blades to #40's and it was a little more durable, they would have been great because they were tiny, and QUIET. I may try the newer model they have... hopefully I can change the blades!
