Hello,
Yeah I see a whole bunch of those around. Microcenter is selling
refurbished and used versions. Refurbished (seemingly by IBM) at
http://www.microcenter.com/single_product_results.phtml?product_id=0147892
CompGeeks has a bunch of 300GL and 300PL systems at cheaper prices than
Microcenter.

I think it is amazing the useful computers you can get for cheap
money these days. My 366 MHz 600e is still useful and I feel that
anything over 300 MHz is good for a general system. I tend to prefer
IBM stuff because you can go to the web site and likely find drivers
and updates. I picked up some P120 and P133 365X/XD laptops for
around $25 dollars and was able to get support on the IBM website.
This was a cheap upgrade from the 365ED I had (365ED is dead now).
It is interesting what you can find at a ham fleamarket or a computer
show/fleamarket. I keep an eye out for IBM stuff. I was able to
get cheap batteries, port replicator, and AC adapters for my 600e.
The batteries are still going strong a year later.
I tend to build my systems and find it interesting the price overlaps
between CPUs. I find in some cases it is cheaper to go to a newer
CPU technology/motherboard/memory than to upgrade the old system.
In one case I found it was cheaper to go with a 1.3 GHz Celeron and a
slot one adapter from Powerleap than to buy a 850 or 1GHz 100 MHz Slot
One P3!

FWIW
I have taken a bunch of 300PL IBM machines - you can get them stripped down
as cheap as $19.00 at the shows - no drives, no memory.
They do have on board video (HORRIBLE), but have an NLX AGP slot, on board
sound (crystal audio, not bad), on board 10/100 Ethernet (Excellent), two
USB ports and all the standard ports.
With a BIOS flash, you can use a one gig P3 (100FSB) or a one gig Celeron,
or the 1.4 gig Tulatin (Celeron) from PowerLeap.com
It can take ANY hard drive (I am running one with an 80 gig and two 40 gigs,
no translation software required).
Coupled with a 64MB Gloria 2 (Nvidia Quatro) video card, it is an awesome
system, fast enough for video capture and DVD burning.
Just a tip if someone wants to build a CHEAP fast system.
