Righto,
The shoes do work, but their effect is rather limited (Best used during the year as part of the regular maintenance)
The small rollers are ok, Alko make a reasonable all metal one that you can fill with either water or sand, but they shouldn't be used if you aren't going to regularly do all the other maintenance tasks as well-because you will cause compaction and could exacerbate your existing problem with moss.....
Edit:
Sorry, I read your post incorrectly. You mean those little do-dads with the rotating spiky things don't you?
Forget it, They fall apart and are jolly hard work. They're also damn near impossible to get in the ground deep enough to do any good job.
save your money or invest it in a good quality brand of teabags so you can at least enjoy something whilst scowling at the moss.
Edit ends.....
There used to be a great little machine you could hire from most Hire shops that was about 14" wide, made, I think, by Sissis, and was a petrol powered roller with decent spikes on it for a good penetration into the soil. Unfortunately, I haven't seen one for a long while now and I expect that good old mainstay of defunct machines (Namely Self and Hafety) is to blame for it's demise.
You can go back to the good old garden fork, or you can also get a person powered, four hollow tined device for the job.
Alternatively, go and chat with the local hire shops and see what is around these days, as you have already suggested. There might be a modern machine that will be suitable for domestic use (The only ones I see to repair these days are to go behind tractors, or are for quite large areas and are very heavy)
I hope this helps in some way....
2nd Edit:
you ought to be aerating once a year to keep the moss at bay, and a good scarify each autumn with perhaps a little light raking in the spring....
Sorry about edits, I've recently had a molar removed due to an abscess under it and might mind keeps wandering to thoughts of painkillers.........
