HA! Option 4.
Buy the DA* 200mm f/2.8 and get 200mm f/2.8 without option one which loses f/2.8 from 50-70mm, although option 2 is also very good. I was planning on getting the Sigma 100-300mm (or 200 with 1.4X teleconverter) after getting my K-7. 35mm f/2, and 16-45mm or DA* 16-50mm, but since you already have the DA* 300mm (not to mention the Sigma is $300 more expensive), you should just get the DA* 200mm new on ebay with cashback. You could probably sell your 300mm for around $800-900, so that leaves you with another $400-500 to earn. The 200mm shouldn't be TOO hard to get, considering you don't have to buy any EXTRA filters (other than UV) due to the 77m filter thread of both your 300mm.
