Personally? I'd wait and check the marketplace on here. You say you can get "a better bass later" but for £200, you could get yourself something now to last quite some time. Ibanez, Squier, Yamaha.... There's a few that do the P/J confit that turn up here often enough and at bargain prices.
I WOULDN'T go for a Stagg, at least try before you buy and try an expensive bass too to get a feel for what to expect and compare models to.
