I really thought that SCM and Felder had a great reputation.
Don't get me wrong, they're definitely a decent step up from the likes of iTECH or Charnwood and most would get on with them fine but when you use them all day, every day, you need a machine that's very dependable and ultimately comfortable to use.
There are massive differences between the bottom end of SCM machines (Minimax) and the top end (L'Invincible) by which point you're getting into Martin and Panhans money and the quality just isn't quite there. SCM's castings are brilliant but the machines are often clunky to use and poorly thought out, too many siestas in the engineering department.
Felder are OK, but wear out very quickly in a moderate-use environment and you find yourself constantly repairing them and replacing parts as they use substandard parts and charge a premium for them, plus the customer service with Felder is generally horrific after they've taken your money. You will find people raving about how good they are, but these are also the people without a spec of sawdust in their workshop so take all "experiences" with a grain of salt, even mine, and formulate your own opinions. As we all know, the only noteworthy thing to come out of Austria was a short ill-tempered man with a funny mustache whose name escapes me.
Altendorf is probably the third best when it comes to panel saws, and they should be good at it as it's pretty much all they make. When it comes to planers I would totally knock the combined planer thicknesser on the head and get separate machines, no matter how little space there is. A combined planer thicknesser is a death sentence for your spine as the thicknesser is at the incorrect height for comfortable work at long periods, a dedicated thicknesser is much higher off the ground, and dedicated surface planers are generally much more robust, accurate, and simpler machines than their combined counterparts. I wouldn't bother with buying new planers, the older ones from the likes of Wadkin, Robinson, Cooksley, Dominion, etc have much more mass and are excellently built at a fraction of the cost secondhand, the only negative being blade changing but anyone worth their salt will learn how to do that without much fuss.
Most woodworkers overlook efficiency and comfort, that's why they never make any money and are completely knackered by 50.
