I use Eastwood's European clear when I'm after a gloss fininsh and I use their Rat Rod satin for a matte finish.
I'm sure it's not an ultra premium product, but it works very well in my experience with it.
The gloss only comes in a gallon, but the satin can be had in a quart. The quart of satin, plus the bottle of activator is about $50, plus shipping.
It's more expensive than hardware store polyurethanes, but it's still pretty reasonable. I typically end up using about 3-4 oz per bow, so it's actually pretty economical.
