I wish I could be of more help. For £100-£130 what you will get will be better than hire skates - as long as they fit - but if you progress well and continue skating longer term you may need to spend more. My gut feel is that any boot from a leading maker where the blade can be removed and replaced is probably going to be good enough to last at least a couple of years, unless you progress exceptionally quickly. I can't give advice about specific boots or brands - but I would advise making the trip to a skate shop, even if it means a long journey. It's not like buying shoes - if they don't fit (too big or too small) then skating is just awful. If you do order online, make sure it's not classed as a "special order" which means you can't return them. Some sites charge a "restocking fee" if you return boots.
