Hmmmm since you mentioned Prince, I recommend the Prince T22 its the MOST comfortable shoe I have ever worn period.....regarding durability, I cannot give you a detailed information as I only just got the shoe since Feb 2011,so far the sole hasn't worn out yet.

I think pooh88 can get you the Prince shoe around RM260-275 or less, I am not 100% sure on pricing, you can also give vobs a holler, price should be around the same, but to be 100% sure, PM both these wonderful sellers, and try and score a good deal for yourself!

I have heard the Prince Rebel is quite comfortable, but the sole does not last that long, its very light as well.

Get the new asics resolution 3 man. Very nice looking . Or the 2 which is sold in topper I think. Alot of pros using em. Those without sponsor.

Well it does give me a secure fit coz I have wide feet,cushioning is unsurpassed, some may find it too soft, for their liking, and some may this is exactly what they are looking for.My suggestion is go to a store, try the Prince T22, with your tennis socks, and walk around for 5 mins, if you like buy em, if you don't, look for another shoe.

I'd recommend Barricade 6, however you may need to go half a size higher if you have slightly wide feet, the cushioning is not on par with the Prince T22 but it is ample, gives off an aura of stability, however I have read that some people rolled their ankle with this shoe, I suspect they need to wear mids, or a ankle brace, I think durability for this shoe is a given, Barricades selling point is its excellent durability.

You could try Nike Court Ballestics 3.3
I personally am not a fan of Nike as the soles wear out extremely fast when I wear em, however I am dying to try these shoes hahahaah. Heard they have decent durability and the fitting is very good as Nike has used a new lacing system where when you lace up, the inside's conform to your foot dynamics, is this marketing jargon ...dunno...have read reviews on talk tennis warehouse that this is true it works....
If you can find one store that has these 3 shoes, go to the store and test em...:-p

I am with kev, even though out of budget, just delay buying a shoe now, and just save abit more, I think long term it will save you some money. Choice is yours lah...just stating my opinion.

I will order Yonex Supergrap Black Overgrip.  Who wanna share? RM4/pc
