orbot vs challenger

[MikeB]

I think it's hard to beat the performance and convenience of a Challenger op for residential. Light weight, easy to handle and almost no learning curve. Use 19 inch cotton or micro beast type pads and good chems like releasit or John G's abstraction vlm. You won't ever have to apologize for poor results.
P.S. the trinity renewal systems Conquerer is basically the same machine with maybe a larger motor.
