British micros for sale / trade at VCF

I thought it might be a nice idea to bring some 8 bit British micros to VCF. Having measured my suitcase & dug out my roll of bubble wrap here's what I reckon I can bring. The machines won't be boxed but I will bring power supplies (220V) for those that won't work off a generic PSU (Dragon, QL). The BBC has a built in PSU, the electrons need 19V and the spectra 9V. I'm open to offers, either money or kit, my aim is more to defray my airfair than to make a profit. Of course, if anyone's looking for anything in particular that's more common in the UK than the USA do let me know. Best regards Rob 3 off Acorn Electrons - working 6 off Sinclair ZX Spectrum 48K rubber keys - 5 working, one with minor keyboard fault (B and N keys) 2 off Sinclair ZX Spectrum + 48K - one fully working, one with some keys not registering 2 off Dragon 32 - working 2 (or possibly 3) off Sinclair QL - all with some keys not registering. 1 off Acorn BBC Micro model B with DFS (floppy disk interface chip - less common) - working. I may be able to bring a drive as well. 1 off Cambridge Z88 Possibly 1 off Oric 1
