Alternative domain host (parking)

[SKA]

I have 3 domains parked with Network Solutions, which becoming costlier to renew.

Any reliable host to whom I could transfer/renew these domains to - any ideas?
I dont have any websites yet, I just need the domains parked with private registration/similar security.

Is it easy to transfer my domains out of Network Solutions' clutches ?

Grateful for any tips
