Hi Ben, my first baler(which I learned to use, hitched to a non-live Dexta)! was a Jones Blue Super Star baler. The Jones company was based in Corwen , Clwyd, North Wales and as such would have local "provenance" to you!
They were very robust, and compact balers, with either a long or short drawbar, depending on the original spec. mine was a short drawbar model, and suited the Dexta so well, it was possible with practice to change gear when baling, without using
the clutch!Another plus was that it was the same colour (nearly) as the tractor, and looked very smart.
Nowadays I have an International 445T baler, which just about copes with a 40 foot swath of straw, something neither the Jones or the Dexta would have been happy with!
Jones Balers were taken over by Allis-Chalmers, and then passed Bamfords, who made and sold the same baler for years afterwards with very few modifications, except the colour!
One further point, whatever brand you choose, you should be aware that even a fairly small baler will be close in weight to a Dexta, and always be aware, that your handbrake may not be enough to hold the baler still if you need to dismount for any reason, especially if the P.T.O. is running
