Dremel 1680 v 1800

[allpurpose]

So I'm considering one of the two, a 1680 or 1800 and other than one being 16" or 18" and the 1800 has the side disc sander is there a great deal of difference between the two? I'm certainly not bent on Dremel as a brand, but I've seen both for sale (used of course) far cheaper than many others on the market.  I like the idea of what appears to be quick blade change at least on the 1800, not sure about the 1680.. 

I haven't read too many negative comments about the 1800, but have seen a few negatives about the 1680..

My current scroll saw is an old 2 speed Dremel I'm forever having to modify and blade changing is a regular PITA.. I  can no longer tighten the bottom clamp sufficiently without the risk of snapping an allen wrench. I've broken two already .

So how does the 1800 fare compared with the 1680?

Thanks

I bought a refurbished 1800 back in 2007 run it until 2009 when i bought my DeWalt.. The 1800 was a decent saw.. and like many saws.. it had vibration in various speeds but smoothed out at either lower or higher speeds.. I liked the sander on the side.. My biggest issue with it ( I believe the 1680 is the same way ) was the connecting rod at the back of the saw.. the one that connects the upper and lower arms together.. Dremel didn't use any bearings in this piece and it is just connected with roll pins.. the roll pin being hard steel would wear out the holes in the rod.. and before you know it.. your blades no longer fit into the saw without cutting off 1/4 inch.. because of the wear in the connecting rod part.. this rod is no more than a piece of flat steel maybe 1/8 ish thick with hole on each end for the roll pin to go through.. 

If you're mechanically inclined and able to take one apart to do this repair every so often.. not a bad saw.. The first time I did this repair I order the part.. when I found it to be just flat steel.. I started making my own, LOL  and if I was to have one again I'd probably figure out a way to put a bearing in the flat steel.. I think that would prevent this issue.. 

I made quite a lot of stuff with that saw..  and enjoyed using it.. just was annoying to have to take it apart  to replace that piece every so often..

I used the 1800 for years before I bought a dewalt and now an ex21. My friend had the 1680, to me the 1800 was more user friendly. all the controls tension release included were in the front of the saw. If I had to choose between the two I would go for the 1800.

Thanks folks..as far as taking it apart periodically my old 2 speed might as well be a FORD, Fix Or Repair Daily..lol

The motor is fine still and vibration isn't really an issue, but the clamps...they are the biggest reason I'll put off doing anything that requires me to drill a hole and thread the blade through.. It has more than enough power, but since I no longer have the patience to fiddle around with tiny parts and I have the shakes from time to time it's just not a fun machine to deal with. I've considered completely disassembling it to use the parts for a different machine altogether..
