Thank you very much for the valuable suggestions and knowledge. From all models you mentioned, I decided to order the Sirui T-005X (with C-10S Ball Head) via ebay, because the price is within my budget (90 euros shipping inclus), and its size and weight are very attractive. I'm using a Pentax KP with a collection of DA Ltds, the bulkiest lens being the DA* 16-50, so I'm not very likely to get to more than 1.5kg at any point, so I think this tripod will serve me very well.
Admittedly, I have almost no knowledge of tripod prior to this question. I didn't know that attention should be paid to the ball head too. I guess this is one of the reason why my no-name tripod is difficult to use (almost impossible to have a perfect horizontal or vertical shot).
Thank you again for the help.
