PSU advice needed.

Hi to all.
I am going to be designing a psu for one of our products.
It's going to be 220Vac in 13V dc (~15 - 20W) out.Must be
isolated.Reasonable regulation.
It will charge a battery (13.8V) and power a logic board(with its own
post regulator)
Cost is a big issue here. Smaller the better obviously.
I am leaning towards using one of the Topswitch line of switching regs
for the job.
Quick look shows TOP244 as probably being suitable.
Does anyone have any better / cheaper suggestions for tackling this
job.
Cheers
Rob
