Both are good tools. If you are only doing a few bearings a year for yourself and a couple of mates, the OFNA kit is cool. If like me you are changing quite a few sets of bearings, the Hudy engineering, and the versatility and speed of use of the Hudy tool make it a better option.
None of the Hudy stuff is cheap (like their drive pin tool etc), but they do make excellent, strong, long lasting precision tools that do make the job easier, which is why I reckon their stuff is worth the extra $$
NB: The Hudy tool is very similar to the GRP bearing tool that was around a while ago, until they burnt the factory down and destroyed everything
. I think they are on the market again now, but are way more expensive than the Hudy unit (but also include a sleeve puller etc).
The Hudy tool is an exact copy of the GRP tool..I bought a GRP a while ago for 30 bucks delivered cause 3 of the 6 jaws on the rear bearing grip had broken off..still worked fine with a bit of jiggling..The GRP units though were sold as complete separate units for .21 engines or .12-.15 engines ..and at $199 a piece..ouch..hudy sells two different sizes of jaws for the two engines and you can easily pull the center shaft (locks with a grub screw) and change them so you only need one tool for both engine sizes.I bought a set of Hudy .21 jaws to try on my GRP unit( $13 delivered from rcmushroom) and they are direct fit..just better quality steel IMHO. The center shaft on the GRP is just threadlocked solid into place instead of a grub screw.bit of heat and bingo..new tool..
The sleeve puller grizz1 is just a plastic collar that fitted over the 14mm bearing puller.It's the only bit I was missing from my kit but I'm pretty sure the exhaust gasket from a .12 size engine will do as a replacement.
