What type of ranges are you planning on shooting?
With most quality 30mm tube scopes,you can shoot pretty far without the need in a 20moa base,most have a decent amount of vertical adjustment.
If you plan on shooting past 600,then they come in handy,but it will depend on the choice of optics that you plan to use.
All of my LR scopes have 100moa of adjustment,most hunting style scopes have around 50moa of adjustment.You have to remember that number is from top to bottom adjustment of the reticle,so if the crosshair is centered in the reticle you have half as much adjustment available for adjusting your scope for long range shots
For example,If you shot a Hornady 165gr SST bullet that had a velocity of 2960 fps you would need to adjust your scope an estimated 12.5moa at 600 yards with a 100 yard zero,and an estimated 31.1 moa if you were shooting at 1000 yards.
With most hunting style scopes,adjusting it for a 600 yard shot is possible without using a 20moa rail or rings,but shooting farther will need a scope with more adjustability or a 20moa rail.
Gunnut07 listed some good bases,I prefer to use Ken Ferrell bases but also use EGW and Weaver's picatinny style rail's on all of my rifles.
I will only use Burris Signature Zee rings with any of my scopes.You can use the inserts to get 0moa,10moa,or 20moa without having a 20moa rail on your rifle.These rings will also keep your scopes from getting marked/scratched from the rings.
If you are really wanting to shoot at longer ranges,you really don't want to cheap out on the optics for your rifle.My cheaper ones start in the $750-800 range and go up to the $2k range.You can't shoot,what you can't see!
