Singapore Thai Embassy

I've done a search and have not really found a definate answer.

I have now 2 back to back 60 day tourist visas and am planning my 3rd for June.

My question is. although I understand Singapore is stricter in applying visa regulations, eg they require to see a departure ticket from Thailand and 1000USD. However, will they issue another back to back Tourist 60 day visa ? I have read something about requiring a 30 day break between touist visas - but not sure if this is correct.

Does anyone have any experience on this matter ?

thanks
