I had the old Palstar AT-Auto and now Palstar HF-Auto.  I wanted one that didn't need CIV or control cables to track changes on the radio which is a K3.  At the time I bought the K3, there weren't many, any if at all, that was RF sensing. Only Palstar came out with one at the time I needed a tuner.  It still works great.

I have the MFJ-998 and no issues here running up to 1.5kw.  In the future I'm looking for an upgrade that will provide a better match.  I've heard that the variable type tuners will match to a 1.1 to 1.  The MFJ in most cases won't match it to a 1.1 to 1.  I do like the feature of auto band switching and frequency tracking.  With RF sensing one still has to perform one extra step.  Any mistake there could be detrimental on a SS amplifier.

The new Alpha tuner looks interesting so is the price.  They are literally just down the street from me.  Perhaps I'll go there to check it out once it's released.

I second what Jonathan W6GX writes about the MFJ-998.  More often than not this tuner will provide a 1.5-1.3 to 1 match even if you set the target SWR in the menu to look for a 1.1 to 1 match.  I can easily fine tune it to a 1 to 1 match on all bands (160-10) except 12 meters (1.4 to 1) best match.  My antenna is a 160 meter OCFD.  I frequently run 1KW SSB for rag chewing and 800 watts RTTY for amplifier tuneup purposes (all bands) no issues.  I was skeptical about purchasing this tuner because of general quality control issues but I have been pleasantly surprised.  If this tuner continues to work like it does now it will be a winner in my book.

I have been using the 998 for about a year, I purchased it so I could use my Swan MKII amp on 17 & 12 with a 2 element 20/15/10 quad as well as get the SWR down on the low end of 10. It has been perfect including 2 contests where I could hop anywhere and have a perfect match with no tuning. It interfaces with my FT1000MP for instant tuning and is very fast, the memory feature is great. I was concerned about getting it because of what I had read in reviews but sure glad I did.

If you get the chance grab a Palstar AT Auto like the others have suggested. I see them on here going for about $1000 from time to time. They are workhorses and Don Kessler supports the crap out of it.
