Love the practice photos - check out Lens baby and Holga lenses - they are both reasonably priced and I have wide, pinhole, macro and fisheye for my Pentax DSLR. ALSO I bought all my other lenses secondhand on eBay, I have a telephoto lens that was $19.99 secondhand and is in mint condition.
Oh yes - it's been so long since I've bought new glass I didn't even think about Holga lenses (I've played with one a long while ago that was a friends!) I really should look for a second hand one, because this shooting is just for me no real need for it except it makes me happy
