Go soil to start with and 1k is quite adequate, shop around and read. You should know your requirements.

Unless latewood, GK, or SA (the good guys) come onto your thread saying things - you must read between the lines of certain posters here, your question is FAR too general.... however I say 1K is well enough to start up - no problems. Look after the pennies and the pounds/dollars will take care of themselves!

Good luck - Hall x
