Walmart offers the Dremel 120-volt Variable Speed Rotary Tool Kit, model no. 4000-2/30, for $55.14. Opt for in-store pickup to cut it to $41.96. (Amazon offers it for the same price for Prime members only.) That's $16 under our mention from last month and the lowest price we've seen. (It's the best deal now by $23.) It features variable speeds from 5,000 rpm to 35,000 rpm and includes 30 accessories, two attachments, and carrying case.
