removable casters

[vertigo_]

I know u can get the track-loc removable casters from mesa ...but for a set of 4 + plates , its like 90(shipped). Can you guys recommend me other options for wheels on my 2x12 rectifier cab, which will be cheaper. I don't want permanent casters on it.

Any help?

Any other caster is gonna require you to drill a hole in it. The Mesa ones are best IMO
