Example power supply:

36 Volts DC @ 20 Amps

That's a little too much power for my needs. I'd pay ~$60 for a complete 24-30v @ 10amps. Unfortunately, I already have the cap, bridge rectifier, and fuses but being able to buy a toroid of those specs for less than the $80 plitron wants would be great.

BTW, I'm not seeing any poll buttons..

Regulated or unregulated???

Big difference in cost potential.

Thus, you may want to rephrase the question.
