Impreza WRX Suspension

[Geo22]

Hi All, I want to replace the suspension on my 03 WRX Wagon as the shocks have about had it.

I'm thinking about upgrading from stock but I’m not sure what to go for. I don't want to spend too much but I do realise you get what you pay for.
I've seen the below kit online and wondered if anyone has used them or has any better ideas for the same kind of money?
