Standard code readers are cheap because they are generic and give the EOBD2 information, if you want specifics they are expensive to mimic the manufacturers gear (FIAT Examiner, Mercedes STAR, etc)
SPi were before the standard came in and in common with other manufacturers Rover had their own specification.
The code readers have gone up in price as fewer of them exist. As garages cleared out their old Sykes Pickavant, Crypton and Snap on sets there was a sweet point when they were cheap but now you are lucky if they are less than a few hundred pounds.
They are still out there if you do your homework and watch the auctions, realistically like anything else the market dictates the pricing.
Don't forget that the Sykes Pickavant ACR was around £500 when new with the GM, Ford and Rover pods plus leads and the last ones were over £1000 including the latest MAP pods
