If you have the budget, i say do it to the T's if you want. I like the fact that the makers of 22's have acknowledged that some customers want the ability to change up and personalize their products. keep searching the web and you'll find a kit in your price range.
for me, the add on kits are a way to show your individuality.
remember the phrase... "This is my weapon! There are many like it, but this one is mine!"
I have personally heard different customers complain to the sales clerk at local gun shops over the years that they would pull the the trigger on the sale of a weapon if only it came in xxx color (or feature, or a shorter stock, etc). people want what they want.
