Thanks for your reply. Opticron have been on my radar. I have not come across some of the models to mention though, particularly Imagic, I will have a look at them, thanks for the tip. Yes Hawke seem to be a popular choice. I did come across one report of the bridge breaking open on one Hawke model, cannot remember the model number now.If you're in the UK then Opticron should be on your radar, they are like the UK version of Vortex in a way, producing excellent "bang for the buck" glass with great optics for the price and great warranty support. If you want to go for something smaller and lighter with very good optics, your budget should allow you to track down a Traveler 8x32 BGA ED which is well reviewed and extremely light. The discontinued Countryman HD 8x32 and Verano HD 8x32 are both also excellent with some more heft (~600g instead of ~450g) if you check around the used market.
If you want something more full sized, I would bet you could find the Imagic 8x42 BGA VHD or the prior model DBA VHD in your budget if you search around for clearance sales or 2nd hand. These are EXCELLENT binoculars that are only marginally inferior to the best costing thousands.
Hawke is also a good budget brand that is well reviewed, their Frontier 8x42 ED-X is a very good mid-level binocular and within your budget on sale: https://www.harrisoncameras.co.uk/pd/hawke-8x42-frontier-ed-x-green-binoculars_38410
