last year Lowe's did a BF deal which is similar but not as complete as the 'toolboxx' they sell for $299. This does not include the HD jig, fasteners or bit, but otherwise is a more-than-typical K4 kit. I want to say it was 79 or 89.
With the K5 kit being the new hotness, they will probably put together a K4 kit similar but it might not happen soon since the ads are all out.
There are 2 versions of the K4 also, one where the handle clamps on the 'tabletop' side of it, so you have to reach around the workpiece to clamp it; and one where it clamps upward on the 'front' side below where your drill will be. I have the first kind and haven't found it inconvenient at all, but if you work on big pieces you might want the second kind. I haven't seen as many kits with that one, it pretty much stays at full price.
