im looking to pick up a cheapish multi track tape recorder. something akin to a porta studio or those various yamaha 4-tracks ive used in the past (in fact especially one of those, i like them)
also, a midines, PAL preffered to avoid stressful tuning/ modding issues, though not essential i suppooose
a korg er-1
additionally, a gba sp on the cheap, condtion not important as long as it works, is lit and the buttons arnt gay 
to trade I have a zx 48k speccy (with kempston mouse, and a loooad of preipherals) ,
a speccy i28 +2 (built in tape/ ay sound!) with RAM music machine MIDI sequencer/ midi enabled 8-bit sampler/ 8-bit delay!!, note, am only gonna swap this one for the midines)
a spare SID 6851 (or is that two? unsure),
a c64+ mssiah (8580 r5 sid inside)
a casio sk100 super duper sampling keyboard (gooogle eet)
a casio pt-30, which in all fairness is amazingly sweet, (most fully featured chord selctions than any of this type) however I have rinsed the sounds, sampled them, used them so much frankly i wouldnt care if i didnt hear one or a vl-1 ever again
a pss- 680 2 op fm synth (midi, midi drum module, 6 track sequence recorders etc)
mini kp which im in the process of swapping off a friend. I may be inclined to trade if it would make any difference to anyone!
cheers!
