Try going to a hamfest and picking up a good used three-output lab supply
with meters and current limiting. I picked one up for $5. Sometimes you can
get some real bargains on used stuff. With the summer season upon us in the
US, there's a hamfest (electronics flea market) almost every weekend within
driving distance. Who knows what else you can pick up. You can check the
ARRL website for a hamfest in your area.
