Hi @MiaMon, welcome to the community.
The Kambrook KBM300 isn’t a model available new anymore and has been as a result removed from the Kambrook Australia website.
The Panasonic SD 2501 is available new and recently has been heavily discounted by some retailers (~$200 down from ~$300), which may indicate it may be a model runout.
I can recommend a Panasonic machine as we have four, three SD200s and a SD-2501 (see photo). We have also had a Sunbeam BM7850 and old Breville machine. Haven’t used a Kambrook, but think it is likely to be similar to the Breville. Neither the Sunbeam or Breville make a loaf as good as the Panasonics.
If you plan to buy a breadmaker, I suggest to look out for a second hand model. Breadmakers are an appliance which are often with good intentions to use regularly, but fall by the wayside for many users. As they are a reasonable size appliance, they are often sold second hand at considerable discount. For example, an older working SD200 can be bought for as little as $20. SD2501 is under $100. We have bought second hand ones in the past and they are still working well.
Our Panasonics have baked 100s of loaves and still going strong. We use each one on average every two days.
The second hand Sunbeam we had stopped working after about 100-150 loaves. It had a circuit board fault commonly found by many users and not fixable.
The only issue in three years has been a belt drive which failed on a SD200. Spares are buyable but we decided to buy a replacement second hand one and use the other for spares.
If you are buying one, buy a Panasonic.
