Buying a new wheel

[subaqua]

Thanks subaqua, I did think that I've read pretty bad things about the wheels, would love to see what even a basic wheel can offer! I vaguely understand what you mean about hub bearings, safe to say I wouldn't be attempting that myself! Learning more about bike maintenance is definitely on my to do list.

Not difficult really and once you have the tools you will always have them ( till the tool fairy arrives and steals them as you use them )

Based on your description of the wheel, other people's assessment of its basic (lack of) quality, and your implication that sorting the hub and truing are on the yet to learn/do list, I'd do what you planned to do when you first asked a simple question (your OP): get a new wheel and transfer the cassette. The chain you have on has 'grown up' with that cassette and be fine with it. Only if the chain has stretched then, yes, get a new chain AND a new cassette.
