actually, the 290-310 serious of saws are MUCH easier to rebuild than the "pro" saws.
4 bolts underneath the engine pan, and the crank and bearings, and seals can be dropped out.
No need for special pullers to split the case.
they are harder to "strip down" to that point though, the plastic handle takes a bit of finagling the first time you remove one.
the saws ARE considered heavy for their engine size, a ms290 is the same size/weight as a ms310, with less power.
but, a 310 engine or cylinder is a bolt in upgrade.
I know NOTHING about the shindawa saws.
many people hate the ms290 series of Stihl saws, and that is just fine by me, that keeps used parts CHEAP.
they run and cut well, and are simple and cheap to work on and maintain, and parts availability is great.
the downsides are, the weight, and slightly more steps to remove the plastic covers.

The Shindaiwa 488 and Stihl MS290 are really in different classes.
The 290 is of cheaper construction, using a cylinder that is integral to the top half of the horizontally-split crankcase. This construction is considered to be less rebuildable and more bulky (but cheaper to make) than the traditional vertically-split crankcase and separate cylinder - as used on Stihl's "pro" saws and the Shindaiwa 488.
The 488 is a legendary saw in Shindaiwa's line; the 290, "not so much."
The more direct competitor to the 488 would be Stihl's 260 Pro - you'll notice the specs are much closer, as is the design and construction.
