I've got a few 7 day sets that came off of ebay. Two I never have used as they are vintage and mint, while one was used/excellent condition and I've shaved with that. Mine are all Solingen but one of these days I'll hit on a nice vintage Sheffield set. If I had the $ I'd go for a TI set of maybe Spartacus with natural scales and a barber's notch. As for the variety, besides the set there is plenty of room for individual razors. Good luck on the set, hope you get what it is you're looking for.
