Yeah, I'm not a huge fan of composite/plastic shock bodies; with long suspension travel, for extreme off-road action. Kyosho's EZ series price point is for entry level fun. Again, as long as the shocks don't leak, I think I'd be trying thicker shock oil before giving up on them. I don't know how much you are looking to spend. I don't know if I'd trust a set of $26-ish aluminum bling "big bore" "high performance" no-name shocks sold all over the interwebs. I've seen/read too many horror stories.
Hopefully someone will jump in and has found cheap shocks that work well.
Maybe,
@Ritz413 has some insight on what works in the Sandmaster 2.0's shocks.
What is the length of shocks you need, and the spring rates that are on your AXXE? I ask about spring rates, because that's another issue you may run into when searching for ultra-low budget shocks and wind up with stiffer units than you already have... then a possibility of having to search for springs suited to work with your ride.
Me shootin' from the hip/brainstormin'... eBay chop shop that has Team Associated RB10 shocks taken off new RTR platforms.
