If you want to sample the opinion of the community on the matter, we just had an interesting thread a few days ago, worth a read so that you can make informed choices:
About that Sweepy situation, there are a number of threads on the forum (just search for “sweepy adapter”) about various adapters that people have used/made. If you have access to a 3D printer, it’s easy (see for example that recent thread), if you don’t it’s also possible to use that opportunity to put your Shapeoko to good use by milling one, see for example that thread.
