Default Best MOSFET for output stages

I know, I know, there is no generic, universal best. But I am trying to get your favorite.

Mine goes like this:

1) IRF540/9540: they are cheap, rugged, and impossible to destroy. and I got tons of them,
2) 2sk1058/2sj162: impossible to destroy, low gate capacitance (CFP is possible with this but hard with the IRFs). But they are hard to find and are pricey.
3) IRFP240/9240: I just got some of them and haven't tried. Nelson seems to like them in SE applications.

your favorite?

Will you be trying to destroy them too?

thanks, jackinnj.

I was wondering what those cable folks would do seeing those tiny weeney wires inside of those semiconductor devices,

Have you considered the two British clones made by Exicon
and Magnatec? They are cheaper and the Exicons even have
slightly better specs. Magnatec also has twochip devices in
one package for higher power handling.

You can buy Exicon devices directly from www.profusionplc.com/hitachi.htm
for prices that are at least much better than what I have to
pay for the Hitachi devices here in Sweden. The nice thing is
that there is no extra charge for shipping and handling etc.
as far as I understand. I will probably place an order myself
from them some day. The only reason I haven't done it yet is
that I am somewhat worried about matching, since I expect
one is likely to get devices from the same batch, and so may
end up with N and P devices from batches that don't match
well.

Edit: I just checked out that site again and they have dropped
the prices for Exicons quite a bit since last time I checked, so
they are only around 4 Euro now (+VAT, I think).

How about 2SK1530 and 2SJ201?
