There is no way a product like this is going to cost significantly
less than a hard disk.  The memory is relatively cheap, but once you
add the case, power supply and interface logic it's going to cost you
nearly as much (or more) than a hard disk.

If all you what is a couple of megabytes of ram disk then your best bet
is probably one of the _internal_ memory expansions for the ST.
Personally I'm hoping to upgrade my 1040 to 4 megabytes when the 1 Mbit
DRAMs drop in price some.

BTW, I think I've seen an external ramdisk for the Macintosh.  If I
remember correctly, it was _more_ expensive than a hard disk...
