My first knitting machine was a Silver Reed LK150. I bought it a few years ago when I first started machine knitting - it is a lovely machine to start machine knitting on. The 150 is classed as a ‘plastic bed’ which makes it lightweight and, therefore, relatively easy to move. The bigger machines are ‘steel beds’ - these are much heavier.
I used to knit baby and children’s sweaters on it as my 6 grandchildren came in rapid succession and all the non-knitting mums wanted hand-knit items!
The only disadvantage I found with the 150 was that there was no ribber attachment for it. With many steel beds there is the option to have a ribber attachment. This enables you to knit in rib, make button bands etc. I used to get round this by simply knitting the ribs by hand then placing the stitches onto the machine.
I ended up with 3 machines, 2 with ribbers. As my grandchildren got older they no longer wanted hand knit items and, as I did not knit for myself, I got rid of them all.
I also used to use the Knitting Paradise forum. There are some very helpful member in the machine knitting section.
You are not crazy!
