I have the TRA001, the larger Triton, but I know they have a smaller model that has a plunge base. I am very happy with the way the TRA001 performs.
My major concern is whether you can find parts for older models. Since I don't know the Trend brand, you might search for older models, then try to find collets and motor brush parts. If they are hard to get, then you might find yourself stranded in the future.
Hope this is helpful.
Finally, glad you've joined in the fun, I suspect the Brits will be along soon to give more specific suggestions.
The more I do, the less I accomplish.
