Did you get anywhere with your SMPS design?

I'd quite like to build a bench supply capable of around 250V @ 250ma DC (so around 50W) - with all the usual facilities you associate with a bench supply (variable voltage and current limit / constant current modes) as I hate the thought of powering any equipment under test without a programmable current limit (and display).

I appreciate that a 50W HV SMPS is no trivial task.... I'll be playing in ltspice when I get some spare moments I think....
