Is a Rega P1 worth keeping?

Hello
In thinking of modestly upgrading my turntable from a Rega P1 to something in the 2-to-4k range i wonder, considering the resale value of the RP1, if it makes sense to keep it to play my flimsy popcorn ridden albums of my youth ? 

(it feeds into a McIntosh MA230)

or would the higher TT be able to handle no harm done?

Thoughts ?
