Sorry about that
. I didn't realise that SFX had dropped the line, but in my defence I tend to be a sporadic user of SFX. I note, however, that B&Q (part of the same group as SFX) were selling the Titan for a while and now sell a suspiciously similar
MacAlister plunge saw instead (possibly a bit of price point engineering here?).
I also mentioned the LIDL Parkside saw. I've checked and you do see them coming up on eBay quite regularly. Mr Millard did a sort of mini comparison of it to the Titan
here. However, the Parkside saw
won't run on Makita rails, although that might no be an issue (also note the price that the LIDL saw sells at when it is in the shops - so it might be worth waiting for that if it floats your boat).
Peter has also done another series of videos showing how useful the plunge/track saw is, starting
here which could also be of interest to you
Again, apologies for not being up to date. I'm a regular track saw user with 4 different models, but I'm trade and that's a somewhat different ball park (reliability, durability and long term spares availability being key issues) so I tend to pick-up on the DIY market trends in these saws a little bit late
