VM Innovations offers the refurbished RotoZip 5.7-Amp Spiral Saw Kit, model no. RZ1500-30, for $39.99 with free shipping. That's the lowest total price we could find for a refurb, although we saw it for a few cents less in March. (It's also $62 under the best price we could find for a new one.) It features a 5.7-amp motor, 30,000 rpm rotation speed, canvas tool bag, and more.

A 90-day warranty applies, although it's unclear who backs it.
