I took a look at the T-bolt awhile back and liked it, but it is a bit pricy for a rimfire. I don't know anything about the CZ's other than I'm not real fond of the CZ centerfires. You could also consider a Savage Mark II series. They are well built, affordable and VERY accurate. My brother has one and it'll shoot one hole 1/2" groups at 50 yards with just about every type of ammo he feeds it.

Something to consider.
