WTB: 030 for A1200

[Flashlab]

This one could go rather cheap. But then again not anymore now that I posted the link ;-). 030 cards go for reasonable prices on eBay IMHO.

To download on Amiga you don't need an accelerator but a network card obviously. If you only want to tranfer files from PC to Amiga maybe a PCMCIA cardreader would be easier.

Sure but you won't find that for 35 GBP.

Seriously for browsing and other stuff you do in Workbench Winuae is nearly perfect. Use that and do some classic gaming on your 1200. With a harddisk and that 4Mb card you can install a lot of games using WHDLoad. Transfer files using a cheap PCMCIA network card or card reader.

Costs:

Winuae: free
4Mb card: 10 GBP?
PCMCIA lan: 10 GBP (second hand)?
PCMCIA card reader: 15 GBP Amigakit

All other options will cost very much. A second hand 4000 can already cost more than 150 GBP and then you don't have a cheap network option.
