I have the HD-102EQ f/10 Celestron/Synta Achromatic refractor on an EQ3/4 mount with the diabolical aluminium legs. It has way to much lever arm movement for that size mount but should work well if they really are EQ5 quality mounts. Pitch the legs of the tripod in the bin and put some solid wooden legs on it.
If the refractors from you link are the same as mine, and I'm betting they are, its not a bad little planetary scope, but it has an abysmal cheese grater focuser. Though once you clean the Synta snot grease out of it and regrease it the improvement is quite dramatic. I've even used mine to image through. (see here

After seeing the amount of CA in my f/10 I'd imagine in the faster focal length scope it would be pretty abysmal. It would probably make a good finderscope or guidescope, but too colourful as a regular visual scope.
