The DC28C and DC39 were awesome, just they do get clogged with larger objects that an older Dyson cylinder can handle though. They get clogged just before the bin entry. However they're still powerful, more quieter and don't get stuck in door frames! They look better as well. My favourite Dyson cylinder is the DC39.
I loved the Dc08 and DC19 years ago but I recently got a DC19 again after being used to a DC39 and its a massive downgrade in terms of just feeling chunky and getting stuck in doorframes.
Make sure you get the ERP head with the purple rubber around the head.
Otherwise I'd recommend a Dc05 as well as that's basically a DC04 in the form of a cylinder (straight suction still)
PS the DC08 has 12 cyclones whereas the DC19 has 8, despite looking the same.
