LX-4000, Ilec SB-8/ASR, or B-100 Flight Computer?

I have a functioning B-100 flight computer (version
1.1). My new ship (SZD-59) is equipped with an LX-4000.
The LX has integrated GPS and the B-100 takes a separate
unit (offhand that seems better since new GPS's kick
the crap out of early units) I also have an Ilec SB-8
with the ASR unit, that for 150 Euros can be upgraded
to the latest GPS driven ASR unit. Upgrading to the
SN10B or LX8000 etc is out of the question, and frankly
not necessary for my current set of skills so I am
not looking for upgrade recommendations like that (unless
someone wants to sell me one REAL cheap!) as much as
I am looking for advice on deciding between the three.
I'm leaning towards the Borgelt or the Ilec, but want
to hear opinions as to which one/ones and why. I'm
just beginning X-C, so user friendly is a real consideration
as well.
I know, I know, 50 pilots=60 opinions, but I still
want to know what others think since I do not have
enough first hand experience with any of them to determine
which would be best. Also, if the B-100 is the better
choice, which external (inexpensive) GPS should I get
to use with it?
