[Elecraft] ASTRON RS-35 or SS-30 supply - OK for K2/100?

For a future K2/100 purchase, I want to get a good supply
which can handle the draw of the rig, and not make hash on
the receiver - my antenna is awful and I will pick up noise
near the rig with it. 

The KPA100 manual says I will probably need 15-20A. 

The RS-20 only does 16A continuous, 20A intermittent.
The RS-35 does 25/35 which is probably more suitable.

I'd like to hear from someone with an RS-35A or -35M (meters)
and how they like it with their K2/100. Ham Radio Outlet
has them. I definitely want something with overvoltage
protection and current limiting, and the RS-35 fits the bill.
Whether or not I need meters, I dunno...would be handy to
see what is happening if something is acting strange, but
given the sensitivity to magnetic fields, I'll probably have
to have this linear supply a fair way away from the rig. 

The switching supplies are tempting. There's been lots of discussion
and the ARRL review of the SS-30M switching supply:
http://www.arrl.org/members-only/prodrev/bymfg.html#A
gave it good marks. This also has overvoltage and current limiting,
and handles 25/30A.

Anyway, if someone has either of these two with their K2/100
I'd like to hear about receive hash with them -- using a feedline
or antenna which may pick up supply noise close to the rig. 
I have a randomwire fed with coax (for appearance) and the 
shield is doing darn little good.
