[Closed] new bike? or upgrade?

I have a full suspension bike - A Gary Fisher Roscoe. 26" wheels, 3*9 gearing. I do use it occasionally, but not a great deal

I also have a rigid 29er that sees far more use. Again, 3*9 gearing.

I am coming to the point where I think I fancy some more bounce. I could add suspension to the rigid 29er, or I could replace the old FS with a new (or new to me) bike. The former is preferable in terms of outlay, but the latter might be more fun and get me out riding a bit more.

Ideally, I'd like to standardise on parts and so on, so I don't have to have three different types of this, that and the other.

So, if possible I'd like a 29er full suspension. 27.5 might be acceptable - that way I can carry only a 27.5" tube in the bag (oh yes I still run tubes all round, tried tubeless and wasn't overly impressed) which will (hopefully) fit smaller or bigger wheels as a get-me-home fix

I don't want 10 speed. I've a garage full of bikes and they're all either 9 speed or 11 speed, so 11 speed is probably the way to go - 1*11 or 2*11, the latter might be better for bigger wheels

A dropper post would be useful, but not essential

Brake wise I'd probably swap over the Hope X2s from the roscoe so I have standardised brakes

and the crunch point, I do NOT want to spend a fortune. under £1200 would be fantastic as I can sort that on cycle to work scheme

Suggestions / feedback / offers of lightly used pristine bikes for not very much money most welcomed. I'd been tempted by Transition smuggler that @Alex is selling but as he's a couple of inches taller than me I think the Large might be too big for me

ah yes, I'm 5'9" with a 32" inside leg and weigh around 70kg, so something in the right size would be ideal

thanks!
