I'll asume the Debut 3 is a turntable, right?
As such,along with a pair of speakers, you need an integrated amp, not a power amp. Big difference.
In either case, If you expect a "decent" amp and speakers for the price you stated, you better start looking used.
But, if everything is in good working order and you want to get into records, it's a fair deal. Do you have any records? If not, seriously consider your reasons for wanting to make this move.
