If you want a great portable dSLR with a great line of lens, and a great viewfinder, the pentax is the best choice.
One thing that is commonly overlooked nowadays is the viewfinder. Typical budget SLRs, such as offerings from your favorite Canon digital rebels, and Nikon D70s, both use low quality pentamirror viewfinders that result in low resolution and low magnification. Pentax actually includes a pentaprism viewfinder that you will usually only find on higher end models. This is a critical aspect that is imperative to have accurate manual focusing.
Pentax also has the best compatibility with old lens. You can fit on anything from over 30 years ago with full lens functionality. With a $10 adapter, you can use even older lens that use the screwmount.
Now why would you want to use old lens?
First of all, the price, you can get great lens for a fraction of the cost.
In two weeks, I have amassed a total for SIX lenses for ~$400 from ebay.
SMC DA 18-55mm kit lens - $105
SMC FA 35-70mm/80-200mm circa early 90s -$85
SMC M 50mm F/1.4 circa early 80s from ebay for $55
SMC A 135mm F/3.5 circa late 70s from ebay for $45
Super Takumar 300mm F/4 circa late 60s for $105.
If bought new, such a lens collection would have set you back over $2000.
Aside from the lack of autofocus, the old manual focus fixed focal length lenses have about the same quality as the new lens if not better. In fact, they are in many aspects better. Nothing beats the smooth focus of a manual focusing lens. Autofocus lens in comparison, have loose focusing mechanisms, so the motor can spin it more easily. If you ever used both autofocus and manual focus, the difference is like night and day.
And don't overlook Pentax's quality either. According to Lumious Landscapes, they have the best fast fifty, and their limited line of lenses are the highest quality ever made.
Here are some great reviews of Pentax lenses.

But I've taken pictures that look just as wonderful with another, albeit completely forgotten aristocrat ? the M42 screwmount Pentax Super-Multi-Coated Takumar 50mm f/1.4. This is one of my favorite lenses, in fact. Its results can be simply gorgeous. Of course, to use this lens you'll have to put up with using a Spotmatic, one of the greatest SLRs in history but long in the tooth today. An engineer at a Japanese camera company told me that if this lens were manufactured and marketed today, it would most likely have to sell for $1,200 to $1,500. I got mine for $60.
Here are a few pics I took with it..
Macro with the 135mm F/3.5 with a Leica closeup lens I got from ebay for $5
another macro
yet another one
Sample shot I took with my 300mm F/4 that only cost me $105, this lens would have cost over $1200 new
Don't expect to get anywhere near this kind of sharpness with $200 cheap zoom lenses.
