Nice but quite an expensive way to get one. A ga2100 or ga2110 can be found from sometimes as little as £60 in sales, there are always ones about for less than £100 following a quick google.
Then a mod kit from Aliexpress (yes seriously) for £40-50 plus 20%.
The mod kits normally come with the required tools and the mod itself takes about 5 minutes and no specialist skills.
