hey!, I haven't used a hot-air station yet but I have done the
over-reflow a bunch fo times and I would take the time investment into
making your own rather than the alternative- especially if you are
only oding a few boards per year! Elektor did a great version of the
taoster oven re-flow controlled with an AVR I think, lcd display,
programmable curves, precision control (within reason),, I think the
only complaint was lack of insulation, but you can always stuff with
rockwool or something.
I have used old style black&decker toaster-oven without any
modification a few times but I got a better one now that I still need
to finish. gluk.
