Never mind, it might help some others to understand I hope someone who knows these products can advise you.

Going for an inexpensive solution, especially if you can't examine and hear the amp first, carries the risk of having to fix it up yourself until you're happy with it. You might need to carry out some selective component replacement or rewiring. If you don't want to do that kind of work or incur additional costs, you need to bear this in mind.
