Sweet.... Ok well here is what I would do if I were in your shoes.
I would buy a Spyder Imagine for 120$ leaving you with 180$. Next I would get the essentials out of the way a 47/3000 PE air tank. I love this tank because it is so cheap! This is 80$ leaving you with 100$ for a hopper and little upgrades.
Next a empire reloader for 45$ is awsome. Now 55$ remains for upgrades and shipping. For 35$ a smart parts proggressive barrell will increase accuracy immediatly. Leaving 20$ for shipping and handiling. Which is awsome. But if you dont want the air tank and would rather go Co2 you can go with the second list. All of that stuff will equal 300$ with shipping and handeling or close to it.
