Yes, if you need chain and sprockets, it's well worth considering a quick-release carrier type set-up like the Renthals. There's several types about; I've got a Talon. Greater initial cost, but replacing rear sprockets is afterwards an easy DIY job, as the stock rear sprocket is expensive and fiddley to change. Once you've bought the carrier, replacement sprockets are only around 25 quid-ish.
