K X purchase with or without a 55-300

I'm about to hit the submit button on the B&H site for a new K X, but before I do a little advice is needed. I have a ZX-5 with a Tamron 28-200 3.8-5.6 AF LD lens. I'm 99% sure the lens will work on the K X, but could use that extra 1% from more experienced users. Also, would there be any advantage of purchasing the combo camera set that would include the Pentax 55-300 lens over sticking with my Tamron?

I think you would see image quality improvement with the two kit lens over the Tamron super zoom that you have. The 55-300 is about one stop faster at 200mm than the Tamron and will probably be sharper.

The wide end of the Tamron will not likely be wide enough for you on a Kx and if you are interested in a super zoom, you may want to look at the newer Tamron 18-250 (or Pentax 18-250). It is pretty decent by all accounts.

The K-x is a good choice.
Remember that with the digital crop, your Tamron 28-200 will not be as wide as you'd expect at 28mm - definitely not wide enough for your landscape shots.
On that I'd suggest either selling it or putting it aside to make way for a twin lens kit - combining the 18-55 with the 55-300. With this combination you have the best of both worlds - wide angle enough and good quality all the way to 300mm.

Let me show you the practical side first.
If you already have a Tamron 28-200mm that would work with the K-x, then all you will need would be covering the wide end so, you can just get the K-x kit with only the DA L 18-55mm.
The kit lens would cover the wide angles you would need and you could still make your Tamron a walkaround lens with the reach of 200mm saving on the $$ too since you didn't have to buy the DA L 55-300mm.
If you are not actually hard up on money, then getting the K-x kit with the 18-55 and 55-300mm DA L lens is more you would say?
You could try out the kit combo first and if you like the results, then you can sell your Tamron 28-200mm.
If however, you feel like you are not oftenly using the 55-300 DA L, you can always sell this since this is a very sellable item. It has the same glass formula as the DA 55-300mm which actually a lot of Pentax users want.
The only difference with the DA L and the DA is the mount (metal vs plastic), Quick Shift focus (which the DA L lack) and the lens hood (none for the DA L).
The resale value of the DA L 55-300mm would be about $200-250 (like new/new/mint).
