For $25, go for it!
The 601 is an entirely satisfactory mid-range enlarger, the Componon is a professional-quality 6-element lens (as I recall the earlier model to the Componon-S), it may have a little less contrast than a modern lens but if in good condition should be fine. I believe the 601 comes only with a filter drawer, no multigrade or color head, so you will need a set of filters (either for the filter drawer or below the lens), which will be an additional cost but probably not so much - you will of course also need an 80 mm lens for your 6x6 negs.
