FSX Steam graphics

I am 16 and i love FSX steam edition. I Am looking for ways to improve my graphics and was wondering what is the best product. I would prefer graphics in Seattle or the PNW area and i don't have hundreds of dollars to spend. I looked at products such as Flytampa and ORBX but was wondering which is the best for FSX steam. I also use it o my laptop so i don't have too much storage. Thanks for the help!
