At least with Tramiel at the helm they had a strategy of going for the long tail of the market by selling at rock bottom prices. Once he was gone they floundered around, and almost got beaten by Tramiel's Atari. It's only once they release the Amiga 500 -- which looked an awful like the 520ST case and strategy wise -- and dropped the price that they caught the lead.
When I bought my ST the 500 wasn't out yet, and the Amiga 1000 was priced way beyond my budget. The 520STfm I bought with monitor was around the same price as the Commodore 128, which I was considering before I discovered the ST.
