Like carver posted, hold out for the adjustable sight version.
The fixed sights aren't bad for a plinker, but I haven't seen one yet that was sighted in decent from the factory. Not very good trail guns for popping bunnies, gophers, or other varmints until you get the sights dialed in.
But the adjustable sights are big, gangly, clumsy suckers compared to the adjustable sights on the Ruger Single-Six/Single-Tens though.
I personally prefer the steel-frame ones over the alloy models too...it's just a better balance in my hand though.
Either option does up the price, but I think it's worth it.
A lot of guys around here have been snapping either the .22lr or combo models up due to the low pricetag.
$190 isn't a bad price for the combo up here on the other end of SD but for a single-caliber you should be able to do better.
