In my experience, KAMs have always been the lower end of equipment. But at least what you have (or had, considering your offers) are direct drives, and this is the most important for beginners. For me, and a lot of other people, belt drives are the ultimate nightmare. Having said that, a mate of mine started off and still is using belt drives - and he is more than a good DJ.
If all you're doing is beatmatching, then any direct drive turntable would suffice for a beginner - I got hold of *hand-me-downs* from a mate who turned pro, after a while you will get a feel for what you like - believe me, once you got beatmatching down with decks from crapola, you will enjoy mixing with better decks - and be better on them. I'm old fashioned and like Technics - I will always say no to Vestax purely (and a few of my mates swear by Vestax on their scratchable side) because I played in a Vestax competition once and they were absolutely ****ed - I've played on 15 year old Technics and they are just as good as the new article, but occasionally you will come across ones which have been tanned - which leads onto if you can buy even just 1 Technics 1200/1210, then it's worthwhile. Most setups (as because of the industry standard blah blah blah) will have Technics, so if you ever play in a club, or party then you've got equipment to have confidence in.
As a beginner, you might not want to get too bogged down in equipment - anything is a starting point. I know folk who have blown £1.5k on decks, mixer (most of the money) and amp - and did very little with it beyond 6-8 months. I started with 2x Limit Decks (worse than KAM
imo) and a Synergy Mixer (a big brand knock off) which had NO EQ, just 3 band kill switches - but it was more than enough to learn on - if anything it taught me to be more creative. Once you get a grounding, get the basics and confidence, you will want more, but beginner packages are usually easy to sell on.
You are spoilt for choice in terms of lent vinyl, but if you figure out what you want, send me a wants list as I've got 3000+ records Im gonna offload (and cant be assed typing them all out)
