Just to check: I made the set on farnell.com and it turned out to be only around $35. The only problem is the power transformer which is not PCB mounted (but can be fit in place and soldered by wires). The list is:
Spec Num P/N Euro Total Euro
4700uF 25V 4 1304301 1,32 5,28
470uF 25V 4 1822556 0,164 0,656

But... I'd made the PS by myself. Since the invention of the PS there are many-many improvements in the parts' base.
