[Elecraft] Newbie question

[coca]

Hi folks

I hope I'm in the right place to ask the following questions. I'm in
the UK and am shortly hoping to take my Foundation Licence which will
allow me 10 watts on (nearly) all bands. When I have it I intend to
start my amateur career on HF using CW (Don't worry, I had 10 years in
the merchant navy as an RO so my morse is reasonable :-)) I don't have
a lot of room for big antennas. I suspect the attic will be where I'll
start. I'm not interested in SSB (at the moment) but would probably
like to try some of the data modes later on. Bearing in mind that I
want to spend my money as wisely as possible, do I:

1.   Get a K1 and hope I can sell it on if I decide to upgrade.
2.   Go for a basic K2 and upgrade it as necessary.
3.   Get a Yaesu FT-817 becuse it's got everything built in!?

All opinions appreciated, especially from those in the UK whov'e built
a K1/K2.

TIA!

Richard
