well you get what you pay for. For a small project like a small sump or frag tank, you might be able to get away with a cheapo but you're going to be really limited in what you can actually do, especially with the small table type routers. Those are generally for woodworking and such. With acrylic, if you are squaring sheets and prepping parallel edges for a tank, you need the width of the panel between the fence and the bit and you pass the sheet between them, vs with most wood projects where this is a big no-no, you have the fence at or behind the bit (so a table around the router works)

Personally, Bosch is the cheapest I would go with if you are planning a few tank projects.

Tell us what you are wanting to do, you might be OK with craftsman
