I purchased those machines, and sold my TP-300 within 24 hours of placing it up for sale. ?I have known the dealer you are referring to for many years. ?It is not often that these become available recent model without too much use, and although the timing was not perfect, I found a way to make it happen as I did not think I would have that situation ever again. ?Now that I have them, I feel very fortunate, and while I did not "need" them, it is so much nicer and faster to process wood with separates, and I hope to have them until I can't do woodworking any more.
Personally, I would not get the folding planer infeed extension at this time, especially if you can confirm it can be easily added at a later time. ?I do not think you need support when feeding, but up to you. ?However, on the outfeed side, I think the 1500MM permanently fixed is very nice, especially if you use the "space saving configuration". ?It moves up and down with the table in a way that the wood always clears the overhanging jointer fence that protrudes behind the jointer. ?When you are feeding, nice to know you can feed multiple pieces or longer pieces, and they will not fall off the outfeed end.?
As for the Waxilit auto lubricator, maybe depends on your usage. ?For me, I like the Renaissance along with the Festool green Flies pads.
As an FYI, it is my understanding that you can't get the Waxilit table and the infeed fold-down together. ?One or the other. ?You may want to confirm that with the dealer. ?For me, I got the Waxilit I did not want, and that is of course the tradeoff for used, but for me it was worth it to not get everything exactly as I would have preferred due to the cost savings of used local over new. ?
I know a couple of people who have their machines against the wall and 1 that does not, and I think it is way nicer if you can have room to talk ?behind the planer (opposite the jointer) assuming you have them together. ?I moved a lot of things around to have that footprint, and am very happy I did that. ?
All personal preferences of course. ?Congratulations. ?
