While not a particularly low budget item I upgraded an original
IBM AT (early 6 mhz model hopped up to 8 mhz) with an AOX Master
386 board.  This board costs about $1000 I think.  The performance
is very good on everything except floppy disk access.  I run
Desqview with 386Max and get true multitasking.  In order to
maximize the performance I got I also bought AOX's companion
32bit memory board which was quite expensive (about $1500 with
2mb).  You will not get quite as good a performance boost without
the memory board but it will still be a true 386 with substantially
better performance than an AT.  Oh, I got the 20mhz AOX board - I
think they have a 16mhz version for less money.
Overall I'm pretty pleased with the upgrade, although for $2500
I could have bought a whole new computer...
