Many thanks for the replies.
It's early days and I'm not in a hurry so will wait to see what turns up on here and other forums where I've put the request.
With regards to budget - I don't have one for two reasons.
First I'll pay the right money for the right scope - quality items cost more to purchase but (generally) hold their value if well looked after. Therefore I am not spending money, I am acquiring something that keeps it's value which, over time and when I sell it, will give me a decent return - so the "cost" is minimal?
Secondly I have noticed adverts where a budget is indicated that sellers appear who are optimists whose items seem to increase in price to suit the budget stated. Nothing wrong in being optimistic but that differs from being realistic.
