I would buy a second hand stanley no 4 and restore it and learn to sharpen it. The time spent will be invaluable in the future and if you move onto more expensive planes you can always turn the stanley 4 into a scrub plane. I would however get a bedrock deign 5 1/2 if you plan to use shooting...
Only 6 months old has a small nick in the chip breaker. Would like a good home so will discuss offers circa £90 if and when they come. Oh also have spare blade!. South East area.
