Honestly,
if you truly want a good bullseye pistol you would be stepping up to one of the following pistols.

If you want a US made 22 pistol, I'd say your only choice would be the S&W 41.
Don't rule out the Russian IZH35M as well. They aren't being imported anymore, but you can still find them for sale. I have one and would recommend the IZH.
The Buckmark and MK series will be alright for an entry level bullseye, but if you want a serious competition pistol, I'd get one of the ones that I mentioned.
